Several studies have been conducted to show that the negative effects of fluoride on human health outweigh the positive ones. In order to improve oral health in school children, drinking water has begun to be fluorinated in the US since the 1940s. However, it now appears that fluoride is harmful to the developing brain, it can also damage the kidneys, causing others and dysfunctions in the human body.
74% of US public water systems are fluorinated. The optimal widely recognized fluoride level is set at 0.7 milligrams per liter of drinking water.
Fluoride and Kidneys
According to study published in Environment International in August, researchers noted an unsettling link between low-level chronic exposure to fluoride in public drinking water and complex changes in the function of both kidneys and liver in young people.
Kid‘s kidneys secrete 45% fluoride, adult’s kidneys secrete 60% fluoride.
Children who drink fluorinated water are more likely to have kidney damage and Chronic Kidney Disease later in their later lives.
The findings also suggest that children with poorer functioning livers and kidneys are at a greater risk, as their bodies absorb larger amounts of fluoride than a child with healthy functioning kidneys and liver, with potential side effects being renal system damage, liver damage, thyroid dysfunction, bone and teeth diseases and impairment of protein metabolism.
Fluoride and IQ
An observational study, conducted by researchers at York University in Ontario, Canada, found that children whose mothers drank fluorinated water during pregnancy had lower IQs. Children were evaluated at the age of 3 and 4 years.
The study, published in the journal Jama Pediatrics in September, states:
“To our knowledge, this study is the first to estimate fluoride exposure in a large birth cohort receiving optimally fluoridated water.”
“These findings are consistent with that of a Mexican birth cohort study that reported a 6.3 decrement in IQ in preschool-aged children compared with a 4.5 decrement for boys in our study for every 1 mg/L of MUF.”
“The findings of the current study are also concordant with ecologic studies that have shown an association between higher levels of fluoride exposure and lower intellectual abilities in children.”
“Collectively, these findings support that fluoride exposure during pregnancy may be associated with neurocognitive deficits.”
Fluorized water has no benefit for pregnant women. Therefore, they were advised to avoid it preventively.
Every citizen should be free to choose whether or not to drink this water. The policy of fluorinating drinking water, in force since 1950, needs to be revised.
